Description

Technical Field

[0001] This invention relates to the field of installation frame technology, and in particular to a prefabricated installation frame for building electromechanical equipment. Background Technology

[0002] Building electromechanical equipment is a general term for equipment in buildings used to provide facilities such as electricity, lighting, air conditioning, communication, fire protection, and security. These devices typically include electrical systems, lighting systems, air conditioning systems, communication systems, fire protection systems, and security systems. The normal operation of building electromechanical equipment is crucial to ensuring the normal use and safety of buildings. The main goal of the installation frame is to ensure that these electromechanical devices can operate safely, efficiently, and stably, and to provide a comfortable environment for users inside the building.

[0003] A search revealed that Chinese patent document CN222316590U discloses a prefabricated installation frame for building electromechanical equipment, including a support rod and two fixing plates. The support rod has insertion holes on both sides of its top, and a limiting mechanism is provided on both sides of the top near the insertion holes. Each limiting mechanism includes a vertical plate fixedly connected to it, with two limiting rods slidingly passing through the vertical plate. The vertical plate also has two circular holes adapted to the limiting rods. The two limiting rods are fixedly connected to the same second inclined toothed plate on the side near the insertion holes. This patent provides greater flexibility for the installation of building electromechanical equipment, allowing adjustments based on actual needs to meet the requirements of different equipment and spaces. It maximizes the use of space within the building, improving space utilization, and makes the installation process more efficient, shortening the construction cycle and reducing project costs.

[0004] Based on research and existing technology, it was found that after the frame height is adjusted, when the self-weight of the electromechanical equipment it supports is large, diagonal bracing (such as diagonal struts) is required to counteract the overturning moment caused by the equipment weight and improve the overall structural resistance to lateral displacement and instability. However, although the aforementioned device has a height adjustment function, it does not include such diagonal bracing. Furthermore, it should be noted that the installation position of the diagonal bracing is significantly correlated with different frame height parameters. Even if the angle of the diagonal bracing remains unchanged, the connection point between the diagonal bracing and the main frame needs to be adaptively changed with the height adjustment to ensure that the diagonal bracing is always in the optimal stress state and effectively plays a stabilizing role. Summary of the Invention

[0005] The purpose of this invention is to provide a prefabricated installation frame for building electromechanical equipment to solve the problems mentioned in the background art.

[0006] The technical solution of the present invention is: a prefabricated installation frame for building electromechanical equipment, comprising two square tubes and two support rods corresponding to the two square tubes respectively. The cross-section of the two support rods is square. The square tubes are slidably sleeved on the corresponding support rods. Each of the four sides of the square tubes has an inclined opening that is connected to the inside of the tube. An inclined brace is slidably inserted into the inside of the inclined opening. Each of the four sides of the support rods has multiple inclined grooves that are linearly distributed at equal intervals along the vertical direction. Multiple inclined blocks that are linearly distributed at equal intervals along the inclined direction are fixed on the plate surface of the inclined brace. The inclined brace is engaged with the inclined groove on the corresponding side of the support rod through the inclined blocks.

[0007] Preferably, a mounting plate is fixed to the bottom of the support rod, and positioning holes are located at the four corners of the mounting plate.

[0008] Preferably, the top ends of the two square tubes are jointly fixed with a horizontal tube, and the interior of the horizontal tube is provided with a drive assembly that enables the two support rods to move synchronously and in the same direction.

[0009] Preferably, the drive assembly includes two bearing seats and two threaded rods. The two bearing seats are respectively fixed to two square cylinders. One end of each of the two threaded rods is rotatably installed in the bearing seat. The top end of each of the two support rods is provided with an internal threaded hole. The rod body of each of the two threaded rods is respectively installed in the two internal threaded holes by threads.

[0010] Preferably, the drive assembly further includes a synchronizing rod. Rotating holes are provided at both ends of the cross cylinder. The two ends of the synchronizing rod are rotatably installed in the two rotating holes respectively. A first bevel gear is fixed to both ends of the synchronizing rod and is coaxially arranged with it. A second bevel gear is fixed to the top of each of the two threaded rods and is coaxially arranged with it. The cone tips of the two first bevel gears face the same direction and mesh with the two second bevel gears respectively.

[0011] Preferably, a bracket is fixed to the outer side of one end of the cross cylinder, and round holes are provided on both sides of the bracket. A worm gear is rotatably installed in both round holes, and a worm wheel is fixed to one end of the synchronizing rod and is coaxially arranged with it. The worm gear and the worm wheel mesh with each other.

[0012] Preferably, one end of the worm gear is fixed with a Z-shaped handle, and a rubber sleeve is fitted on the outside of the Z-shaped handle.

[0013] Preferably, two sets of rollers are rotatably installed on both sides of the inclined opening, and the rollers are in contact with the inclined support rods inside the inclined opening.

[0014] Preferably, the bottom end of the diagonal brace is rotatably fixed with a roller.

[0015] Preferably, an electromechanical fixing plate is fixed to the outer side of the cross cylinder, and the surface of the electromechanical fixing plate is provided with multiple mounting holes and multiple straight slots.

[0016] This invention, by improving the prefabricated installation frame for building electromechanical equipment provided herein, has the following improvements and advantages compared to the prior art: Firstly, this invention achieves adaptive bracing adjustment based on the principle of inclined top transmission, maintaining a constant inclination angle of the bracing rod throughout the adjustment process. When the support rod carrying the electromechanical equipment is height adjusted, the combined length of the support rod and the square tube changes synchronously with the height parameter, driving the bracing rod to move radially outward. During this process, the relative distance between the top of the support rod and the top of the bracing rod increases with the increase of the combined length, and the top of the bracing rod and the top of the support rod always remain flush to ensure a stable force transmission path. Thus, it can be seen that during the dynamic process of overall frame height adjustment, the bracing force provided by the bracing rod is dynamically adjusted in a correlated manner with the change of the combined length of the support rod and the square tube, always adapting to the structural stress requirements at the current height. Secondly, traditional diagonal bracing structures require manual disassembly, re-drilling, repositioning, and reinstallation of the diagonal braces after frame height adjustment (such as adjusting the connection nodes between the diagonal braces and the frame, and replacing diagonal braces of different lengths). The operation process is cumbersome and relies on professional personnel. In contrast, this adaptive structure features "simultaneous completion of height adjustment and diagonal brace adaptation." It eliminates the need for manual intervention in the installation position or length of the diagonal braces. The diagonal braces can automatically complete the radial displacement and force adaptation simply by adjusting the height of the support rods, significantly reducing the total time spent on height adjustment (especially suitable for scenarios requiring frequent height adjustments, such as production line equipment changes and workshop layout optimization). It avoids "structural hazards caused by installation errors" (such as loose nodes and angle deviations) when manually adjusting diagonal braces, reduces reliance on the professional skills of operators, and improves the safety and convenience of on-site operation.

[0020] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] This invention provides an improved prefabricated installation frame for building electromechanical equipment. The technical solution of this invention is as follows: like Figures 1 to 9 As shown, this embodiment of the invention provides a prefabricated installation frame for building electromechanical equipment, including two square tubes 1 and two support rods 2 corresponding to the two square tubes 1 respectively. The cross-section of the two support rods 2 is square. The square tubes 1 are slidably sleeved on the corresponding support rods 2. Each of the four sides of the square tubes 1 has an inclined opening that is connected to the inside of the tube. An inclined brace 3 is slidably inserted into the inside of the inclined opening. The four sides of the support rods 2 have multiple inclined grooves 4 that are linearly distributed at equal intervals along the vertical direction. Multiple inclined blocks 5 that are linearly distributed at equal intervals along the inclined direction are fixed on the plate surface of the inclined brace 3. The inclined brace 3 is engaged with the inclined grooves 4 on the corresponding side of the support rod 2 through the inclined blocks 5. From the above connection relationship, it can be seen that: since the diagonal brace 3 is connected to the inclined block 5 and the corresponding inclined groove 4 on the side of the support rod 2, the diagonal brace 3 and the support rod 2 form an inclined top structure. When the support rod 2 moves downward relative to the square cylinder 1, the support rod 2 pushes the corresponding inclined block 5 through the inclined groove 4, so the diagonal brace 3 then moves diagonally downward and outward in a radial direction. Throughout the adjustment process, the inclination angle of the diagonal brace 3 remains constant, and the top of the diagonal brace 3 and the top of the support rod 2 always remain flush to ensure a stable force transmission path. In summary, the adaptive diagonal brace adjustment is achieved based on the inclined top transmission principle, and the entire adjustment process maintains a constant inclination angle. The inclination angle of the diagonal brace 3 remains constant. When the height of the support rod 2 carrying the electromechanical equipment is adjusted, the combined length of the support rod 2 and the square tube 1 changes synchronously with the height parameter, driving the diagonal brace 3 to move radially outward. During this process, the relative distance between the tops of the support rod 2 and the diagonal brace 3 increases with the increase of the combined length, and the top of the diagonal brace 3 and the top of the support rod 2 always remain flush to ensure a stable force transmission path. It can be seen that during the dynamic process of adjusting the overall height of the frame, the diagonal bracing force provided by the diagonal brace 3 is dynamically adjusted in a correlated manner with the change of the combined length of the support rod 2 and the square tube 1, always adapting to the structural stress requirements at the current height.

[0022] Specifically, in conjunction with the appendix Figure 7 As shown, a mounting plate 6 is fixed to the bottom of the support rod 2, and positioning holes 7 are located at the four corners of the mounting plate 6. As can be seen from the above connection relationship, the mounting plate 6 is placed on the ground, and the fixing bolts are passed through the positioning holes 7 and then fixed on the ground, thereby fixing the mounting plate 6 on the ground.

[0023] Specifically, in conjunction with the appendix Figure 2 and attached Figure 3 As shown, a cross tube 8 is fixed to the top of the two square tubes 1. The cross tube 8 is equipped with a drive assembly that enables the two support rods 2 to move synchronously and in the same direction. The drive assembly includes two bearing seats 9 and two threaded rods 10. The two bearing seats 9 are fixed to the two square tubes 1 respectively. One end of the two threaded rods 10 is rotatably installed in the bearing seats 9 respectively. The top of the two support rods 2 is provided with internal threaded holes. The rods of the two threaded rods 10 are respectively installed in the two internal threaded holes through threads. It should be noted that the inner wall shape of the square tube 1 is compatible with the outer wall shape of the support rod 2 (both are square structures), and the inner wall dimension of the square tube 1 is slightly larger than the outer wall dimension of the support rod 2. This gap design ensures that the support rod 2 can be smoothly inserted into the square tube 1, and also restricts the movement trajectory of the support rod 2 inside the square tube 1 through the "anti-rotation" characteristic of the square structure. That is, the support rod 2 is only allowed to move linearly along the axial direction of the square tube 1, completely avoiding circumferential rotation of the support rod 2 during movement. This provides a stable motion constraint basis for the subsequent linear sliding of the support rod 2 by the threaded rod 10 through threaded transmission. Secondly, in the specific operation of the threaded transmission, one end of the support rod 2 is usually provided with an internal threaded hole that matches the external thread of the threaded rod 10 (or a connecting seat with an internal thread is fixed thereon). When the threaded rod 10 rotates under power drive, the external thread of the threaded rod 10 will mesh with the internal thread on the support rod 2. Since the square tube 1 has restricted the rotation of the support rod 2 through the square fit, the support rod 2 cannot rotate synchronously with the rotation of the threaded rod 10. At this time, the meshing force between the threads will convert the rotational motion of the threaded rod 10 into the linear motion of the support rod 2 along the axis of the square tube 1. If the threaded rod 10 rotates clockwise, the support rod 2 will extend outward along the square tube 1; if the threaded rod 10 rotates counterclockwise, the support rod 2 will retract inward along the square tube 1, realizing the precise adjustment of the extension and retraction length of the support rod 2.

[0024] Specifically, in conjunction with the appendix Figure 2 and attached Figure 3 As shown, the drive assembly also includes a synchronizing rod 11. Rotating holes are provided at both ends of the cross cylinder 8. The two ends of the synchronizing rod 11 are rotatably installed in the two rotating holes respectively. A first bevel gear 12 is fixed at both ends of the synchronizing rod 11 and is coaxially arranged with it. A second bevel gear 13 is fixed at the top of the two threaded rods 10 and is coaxially arranged with them. The cone tips of the two first bevel gears 12 face the same direction and mesh with the two second bevel gears 13 respectively. It should be further explained that the synchronizing rod 11, as the core transmission component, is coaxially and fixedly connected to the first bevel gear 12 at both ends (such as by keying or welding). This ensures that when the synchronizing rod 11 rotates, it can directly drive the first bevel gears 12 at both ends to rotate synchronously without transmission backlash, avoiding transmission delays or slippage caused by loose connections. Each first bevel gear 12 precisely meshes with the corresponding second bevel gear 13, and the tooth ratio of the first bevel gear 12 to the second bevel gear 13 is optimized to allow adjustment of the transmission ratio according to actual needs (e.g., when the threaded rod 10 needs to rotate rapidly, it can be designed so that the first bevel gear 12 with a small number of teeth drives the second bevel gear 13 with a large number of teeth, or vice versa), meeting the adjustment efficiency requirements in different scenarios. The second bevel gear 13 is coaxially fixed to the threaded rod 10. When the first bevel gear 12 rotates, the meshing force between the teeth will drive the second bevel gear 13 to rotate, thereby driving the threaded rod 10 to rotate synchronously.

[0025] Crucially, the cone tips of the two first bevel gears 12 are aligned (e.g., both facing the center of the synchronizing rod 11). This design ensures that when the two first bevel gears 12 rotate with the synchronizing rod 11, the forces exerted by each first bevel gear 12 on their respective meshing second bevel gears 13 are in the same direction. This guarantees that the rotation directions of the two second bevel gears 13 are completely consistent, ultimately achieving synchronous and unidirectional rotation of the two threaded rods 10. This synchronous and unidirectional rotation characteristic has significant practical implications. If the threaded rods 10 are used to drive two actuators of a device (such as the two clamping arms of a clamping mechanism, or the two support screws of a lifting platform), synchronous and unidirectional rotation ensures that the movement speed and displacement of the two actuators are completely consistent, avoiding equipment jamming, tilting, or damage due to asynchronous movement, and ensuring the stability and safety of equipment operation. At the same time, compared to driving the two threaded rods 10 separately, the synchronous transmission structure achieved through the synchronizing rod 11 and bevel gear set is simpler, reducing the number of driving components and lowering the equipment failure rate and maintenance costs.

[0026] In addition, to ensure the smoothness and durability of the bevel gear meshing transmission, the tooth surfaces of the first bevel gear 12 and the second bevel gear 13 are usually hardened to improve hardness and wear resistance. Lubricant can also be applied to the meshing point to reduce friction and wear between the teeth, extend the service life of the components, and further ensure the long-term stability of the synchronous transmission effect.

[0027] Specifically, in conjunction with the appendix Figure 3 As shown, a bracket 14 is fixed to the outer side of one end of the cross cylinder 8. Circular holes are opened on both sides of the bracket 14. A worm gear 15 is rotatably installed in the two circular holes. A worm wheel 16 is fixed to one end of the synchronizing rod 11 and is coaxially arranged with it. The worm gear 15 meshes with the worm wheel 16. A Z-shaped handle 17 is fixed to one end of the worm gear 15. A rubber sleeve is fitted on the outer side of the Z-shaped handle 17. As can be seen from the above connection relationship, in actual operation, when it is necessary to adjust the rotation state of the synchronizing rod 11, the worker only needs to hold the rubber sleeve of the Z-handle 17 with one hand and rotate the Z-handle 17 in the desired direction. This will drive the worm 15 to rotate around its own axis within the circular hole of the bracket 14. Since the worm 15 meshes with the worm wheel 16, the rotation of the worm 15 will drive the worm wheel 16 to rotate synchronously through gear transmission. Furthermore, since the worm wheel 16 is coaxially fixed with the synchronizing rod 11, the rotation of the worm wheel 16 will directly drive the synchronizing rod 11 to rotate around its own axis, thereby realizing the subsequent linkage action of the synchronizing rod 11 (such as adjusting the position of the internal components of the cross cylinder 8). More importantly, the worm... The meshing structure of worm 15 and worm gear 16 has good self-locking performance. This self-locking performance comes from the transmission characteristics of the two, that is, only when worm 15 rotates actively can it drive worm gear 16 to rotate, and worm gear 16 cannot drive worm 15 to rotate in the opposite direction. Therefore, when the worker stops rotating the Z-handle 17 and no external force is applied to worm 15, worm gear 16 will remain in its current position, thus preventing synchronizing rod 11 from rotating on its own. This effectively prevents synchronizing rod 11 from rotating unexpectedly due to external vibration, load pressure and other factors, ensuring the stability and safety of the overall operation of the equipment. It is especially suitable for working scenarios that require maintaining a fixed angle or position of synchronizing rod 11 for a long time, such as machining positioning, equipment support adjustment and other fields.

[0028] Specifically, in conjunction with the appendix Figure 5 As shown, two sets of rollers 18 are rotatably installed on both sides of the inclined opening, and the rollers 18 are in contact with the inclined support rods 3 inside the inclined opening. As can be seen from the above connection relationship, the roller 18 is set in order to reduce the friction between the diagonal brace 3 and the inclined opening.

[0029] Specifically, in conjunction with the appendix Figure 6 -Appendix Figure 9 As shown, a roller 19 is rotatably fixed at the bottom end of the diagonal brace 3; As can be seen from the above connection relationship, the rolling wheel 19 is set to reduce the friction at the bottom of the diagonal brace 3.

[0030] Specifically, in conjunction with the appendix Figure 2 As shown, an electromechanical fixing plate 20 is fixed on the outer side of the cross cylinder 8. The surface of the electromechanical fixing plate 20 is provided with multiple mounting holes 21 and multiple straight slots 22. As can be seen from the above connection relationship, the mounting hole 21 and the straight groove 22 are for the convenience of installing electromechanical equipment.

[0031] In summary, based on the specifications of the electromechanical equipment, multiple mounting frames can be installed on the ground to facilitate the installation of the equipment.

[0032] Working principle: The worker rotates the worm 15 by using the Z-shaped handle 17. The worm 15 drives the worm wheel 16 to rotate. Since the worm wheel 16 rotates with the synchronizing rod 11, the worm wheel 16 drives the synchronizing rod 11 to rotate. Utilizing the self-locking property of the worm 15 and worm wheel 16, the synchronizing rod 11 cannot rotate on its own without the action of external force. When the synchronizing rod 11 rotates, the first bevel gears 12 at both ends of the synchronizing rod 11 rotate with the synchronizing rod 11. The first bevel gears 12 drive the threaded rod 10 through the second bevel gears 13 that mesh with them. Since the cone tips of the two first bevel gears 12 face the same direction, the two second bevel gears 13 rotate in the same direction, so that the two threaded rods 10 rotate synchronously in the same direction. Since the square tube 1 is slidably sleeved on the corresponding support rod 2, the support rod 2 can only move linearly relative to the inside of the square tube 1. When the threaded rod 10 rotates, the threaded rod 10 causes the support rod 2 to slide linearly along the square tube 1 through the threaded transmission. When support rod 2 moves downward relative to the square cylinder 1, support rod 2 pushes the corresponding inclined block 5 through inclined groove 4, thereby causing inclined support rod 3 to move obliquely downward. Inclined support rod 3 moves radially outward, maintaining a constant inclination angle throughout the adjustment process. The top of inclined support rod 3 remains flush with the top of support rod 2 to ensure a stable force transmission path. In summary, adaptive inclined support adjustment is achieved based on the inclined top transmission principle, maintaining a constant inclination angle of inclined support rod 3 throughout the adjustment process. When the support rod 2 carrying the electromechanical equipment undergoes height adjustment... At this time, the combined length of the support rod 2 and the square tube 1 changes synchronously with the height parameter, driving the diagonal brace 3 to move radially outward. During this process, the relative distance between the tops of the support rod 2 and the diagonal brace 3 increases with the increase of the combined length, and the top of the diagonal brace 3 and the top of the support rod 2 always remain flush to ensure the stability of the force transmission path. It can be seen that during the dynamic process of adjusting the overall height of the frame, the diagonal bracing force provided by the diagonal brace 3 is dynamically adjusted in a correlated manner with the change of the combined length of the support rod 2 and the square tube 1, always adapting to the structural stress requirements at the current height. In summary, traditional diagonal bracing structures require manual disassembly, re-drilling and repositioning of the diagonal bracing after frame height adjustment (such as adjusting the connection node between the diagonal bracing rod 3 and the frame, or replacing diagonal bracing rod 3 with different lengths). The operation process is cumbersome and relies on professional personnel. In contrast, this adaptive structure has the characteristic of "height adjustment and diagonal bracing adaptation being completed simultaneously". There is no need for manual intervention in the installation position or length of the diagonal bracing. The diagonal bracing rod 3 can be automatically driven to complete the radial displacement and force adaptation simply by adjusting the height of the support rod 2. This significantly reduces the total time spent on height adjustment (especially suitable for scenarios that require frequent height adjustments, such as production line equipment replacement and workshop layout optimization). It avoids the "structural hazards caused by installation errors" (such as loose nodes and angle deviations) when manually adjusting diagonal bracing, reduces the reliance on the professional skills of operators, and improves the safety and convenience of on-site operation.

Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
